Using Excel, an interactive program is designed to simulate the Solow and endogenous growth models to facilitate the understanding of these models for students of growth theory and macroeconomics.

Argues that technical communicators should have a working definition of icons, know when to use them, and understand some of the problems inherent in icon design. Recommends using a workable icon classification system and adhering to some practical design guidelines. (SR)

The Computer Museum in Marlborough, Massachusetts houses old and not-so-old calculators, famous old computers and parts of computers, photographs and assorted memorabilia, computer-generated murals, and even a computer made of Tinkertoys that plays tick-tack-toe. The development of the museum and selected exhibits is described. (Author/JN)

Interactive computer graphics is fast becoming the standard medium of communication between computers and all kinds of users. Reasons for this trend, the technology of interactive graphics displays, software considerations, applications (including classroom and laboratory applications), and future developments are discussed.

Description of the Macintosh personal, educational, and business computer produced by Apple covers cost; physical characteristics including display devices, circuit boards, and built-in features; company-produced software; third-party produced software; memory and storage capacity; word-processing features; and graphics capabilities. (MBR)

This article provides a diverse collection of examples of computer use in elementary and secondary school social studies. Names and addresses are provided for contacting many of the projects. (JDH)

Epigrapher and philologist Bruce Zuckerman, directs an archive of photographs and other images of ancient biblical and related texts. By using sophisticated technical photography and computer graphics, he makes his photographs of ancient texts reveal more than a camera alone ever could. (MLW)

Computational science is defined as science done on a computer. A computer can serve as a laboratory for researchers who cannot experiment with their subjects, and as a calculator for those who otherwise might need centuries to solve some problems mathematically. The National Science Foundation's support of supercomputers is discussed. (MLW)

Argues that graphic images and technologies can be of substantial help to social work practitioners for assessment and intervention with children and families. Suggests a range of graphic tools and techniques, including profiles, ecomaps, sequential ecomaps, contingency diagrams, concurrent graphing, and computerized Visual EcoScan. (DR)

Discusses major features and capabilities of gateway software--microcomputer software packages that act as interfaces between users and bibliographic retrieval systems they are searching--i.e., communication, interface, auxiliary programs. Four programs (In-Search, Universal Online Searcher, Search Helper, microDisclosure) are reviewed and…

General principles of computer graphics are reviewed, including discussions of display hardware, geometric modeling, algorithms, and applications in science, computer-aided design, flight training, communications, business, art, and entertainment. (JN)

This paper contains brief synopses of recent technical progress/projects in the field of advanced learning systems. This issue contains the following 12 items: (1) "Guest Editorial" (Sylvia Charp) concerning the need to provide better learning experiences for all students; (2) "Steps in Developing an Expert Systems Model," as…

One application of modeling is studying the ways in which molecules fit together to form chemical compounds. Describes the forces acting between molecules and how three-dimensional graphical modeling is employed in developing rational principles for drug design. (JN)

Scientists are designing computer models of biological systems, and of compounds with complex molecules, that can be used to get answers once obtainable only by sacrificing laboratory animals. Although most programs are still under development, some are in use by industrial/pharmaceutical companies. The programs and experiments they simulate are…

Provides basic information on videodisks and potential applications, including inexpensive online storage, random access graphics to complement online information systems, hybrid network architectures, office automation systems, and archival storage. (JN)
